APPARATUS FOR DEFINING KEYSTROKE VALUES OF KEYBOARD, KEYBOARD WITH DEFINABLE KEYSTROKE VALUES, AND METHOD THEREFOR

Abstract

A keyboard with definable keystroke values is provided. The keyboard includes an output interface for connecting to a keyboard interface of a host computer; keycaps for receiving operational inputs; a signal generation unit for generating keystroke signals in response to the operational inputs on the keycaps; a storage unit; and a micro control unit (MCU). The MCU includes a defining module for defining keystroke mappings between keystrokes and keystroke values in a user-defined keystroke mode, and storing the keystroke mapping into the storage unit; and an output control module for receiving the keystroke signals from the signal generation unit, reading the corresponding mapped keystroke values from the keystroke mapping stored in the storage unit in the user-defined keystroke mode, and outputting the mapped keystroke values to the keyboard interface of the host computer through the output interface.
